The idea in forming the parts in this manner is to provide means whereby the coffee may -be removed from the container readily and at the same timeprevent entrance of air so that the.

aroma and general original condition of the coffee In this -way ground coffee' may yet be ready to be vended at any time.

It will be noted that by the tight sliding connection of the parts the container is airtight and' remains airtight even during the withdrawal of the coffee, as there is a supply of coffee always at the opening, and this with the wire mesh presents a seal against the entrance of air, though the propellers may force coiee therethrough against the-atmospheric pressure. y

I claim: 1. A coffee preserver of thecharacter described comprising a container having` at the bottom an aperture, a closure plate arranged beneath said bottom but in engagement therewith, said closure plate having an aperture therein adapted to register with the aperture in said bottom, rotatable means connected with the closure plate and positioned within the'oontainer for;y forcing some of the contents of the container from said aperture when in registryand resilient means acting on said rotatable means forvpulling said closure plate towards the exterior surface of said bottom.

2. lA device-of the character described comprising a container of vitreous materialhavinga tapering bottom with an aperture inY onepart thereof, a metallic lid screwed onto the container at the top, a gasket for producing anV airtight connection between the metallic lid*y and the container, said bottom `having an upstanding bead exteriorly around said aperture, and a plurality of raised portions scattered over the exterior of the bottom,` said raised portions being of the same height assaid bead, anvaperturedclosure plate formedto t ,slidingly but airtight against said bead and said raised portions, resilient means for maintaining said plate pressing against said bead and raised portions, and a handle for causing manualoperation of said plate whereby the'aperture therein may be moved into and out of registry with the aperture in said bottom.

3. A device of the character described comprising a container formed with a tapering bottom having an aperture in the center and a discharge opening between the center and the periphery, a pin extending through said aperture, a propeller having a plurality of blades secured to said pin, the propeller arranged interiorly of the container and positioned to force some of the contents of the container through said opening as the blades pass the opening, a cover plate of substantially the` same shape as said bottom tting latwise against the bottom for maintaining said opening closed, `said plate having an aperture adapted to be brought Vinto registry with said opening when the' material ywithin the container is to be discharged therefrom, said cover plate being rigidly secured tosaid pin, and a spring acting on said bottom and acting on said propeller for transmitting strain to said pin whereby said plate is held tightly against said bottom.

' 4. A d-evice ofthe character described including a container having an aperture in the center and an opening between the center and the periphery, a cover plate tting against said bottom exteriorly thereof and normally closing said opening, said cover plate having an aperture adapted to be brought into registry with said opening, a pin secured to said cover plate and extending through said aperture in said bottom, and means including a spring for giving said pin a tendency to move into said container, whereby said cover plate is caused to t airtight against `said bottom.

5. vA device of the character described comprising a container having a bottom provided with a centrally positioned aperture rand a discharge opening at one side of the aperture, a cover plate tting against the exterior face of said bottom and normally closing said opening, a rotatable feeding member positioned interiorly of said container means connected to said cover plate and said feeding member for rotatably mounting said cover plate and said feeding member, and a spring acting on said feeding member and said container for continually pressing said cover plate against the exterior of said bottom, said cover plate having an aperture adapted to be brought in line with said opening, and a handle connected with said cover plate whereby the handle may be grasped and the cover plate rotated as often as necessary to bring said opening and said aperture in the cover plate in registry as manytimes as desired,
